Abstract
An internal combustion engine including a pilot subchamber, a pilot fuel injector having a tip in communication with the pilot subchamber, an ignition element positioned to ignite fuel within the pilot subchamber, and a main fuel injector spaced apart from the pilot fuel injector. The engine includes a common rail in fluid communication with the main fuel injector and with the pilot fuel injector and a pressure regulating mechanism in fluid communication with the common rail for regulating a fuel pressure therein. A method of combusting fuel in an internal combustion engine is also provided.
